Answer

All three listed materials—diamond, graphite, and graphene—are recognized allotropes of carbon. Diamond has a strong tetrahedral structure, graphite consists of layers of hexagonally arranged carbon atoms, and graphene is a single layer of carbon atoms arranged in a two-dimensional lattice. Therefore, this option is correct.

Step 2

B) Diamond, granite, graphite.

Answer

Granite is not an allotrope of carbon; it is a type of rock composed mainly of quartz, feldspar, and mica. Thus, this option is incorrect.

Step 3

C) Fullerene, graphene, ethene.

Answer

While graphene is an allotrope, ethene is not a form of carbon but rather a hydrocarbon compound. Fullerene is another allotrope of carbon, but the presence of ethene makes this option incorrect.

Step 4

D) Granite, graphite, graphene.
